For example, as it is known that in order to cool down compressor set, liquid such as oil or water are sprayed to the rotor chamber of compressor element It is interior.

So, for example the temperature in the exit of compressor element can be maintained in specific limitation, to cause temperature not Can become too low, to prevent that condensate liquid is formed in compressed air, and fluid temperature is not too much high, to cause the quality of liquid Keep optimal.

Injection liquid can also be used to seal and lubricate compressor element or expanding machine element, so as to obtain good Operation.

The amount and temperature of known injection liquid will influence the efficiency of cooling, sealing and lubrication.

The method of liquid injection of the control in compressor set is additionally known for, so that using the temperature based on injection liquid The control of degree, the control is included when more coolings are wished by causing that liquid causes the temperature of injection liquid by cooler Decline.

By controlling temperature, additionally it is possible to adjust the viscosity of liquid, therefore adjust its lubrication and sealing characteristics.

The shortcoming of this method is that the most I of injection liquid obtains the temperature of cooling agent of the temperature by being used in cooler Spend to limit.

The method of liquid injection of the control in compressor set or expander device is additionally known for, so that using being based on The control of the mass flow of liquid is sprayed, the control includes for example spraying more liquid when more coolings or lubrication are wished.

By spraying more liquid, temperature will raise smaller.This can have injection temperation higher, and simultaneously no more than maximum Outlet temperature, so that also without the cooler of oversized dimensions in the case of coolant temperature high.

The shortcoming of this method is the temperature that will be merely able to be indirectly controlled injection liquid.

Known method have the disadvantage in addition when a part injection liquid be used for lubricate bearing when, the liquid will have and spray extremely It is used to cool down the liquid identical temperature of the rotor chamber in rotor chamber.

Actually it has already been indicated that in such compressor set or expander device, the service life of bearing is subject to lack Weary suitable temperature controlled adverse effect.

But when both optimizing, two control between it is functional on interaction, this causes efficiency of element The summations that individually efficiency of control are improved more than two are improved, therefore, control is related to combination, and is not only to gather or side by side.

The interaction of this function is partly due to inflating phenomenon, and the inflation phenomenon is related to the air for dissolving in a liquid Amount.

At least locally cut down by controlling the amount of temperature and mass flow, dissolving air in a liquid, this will increase imitates Rate.

On the other hand, it is necessary to consider sealability, the sealability is partly due to spraying the viscosity of liquid, section due In the available quality flow of liquid.For each operating point, there is the desirable combination of fluid flow and viscosity, this is the letter of temperature Count, therefore two parameters are mutually strengthened.

Preferably, method includes the liquia air of the flow, the temperature of liquid and/or modular conduit part of control liquid The step of content.

Therefore, conduit part can be provided with required device, so that conduit part cannot be only used for separate liquid supply, and And be additionally operable to control its parameters/characteristics.
